Investigators are building an empirical evidence base for real world data through large-scale replication of randomized controlled trials. The investigators' goal is to understand for what types of clinical questions real world data analyses can be conducted with confidence and how to implement such studies.
To determine the incidence and risk factors of ethanol-induced symptoms, this multicenter, prospective, observational study is designed to include patients in Korea who are receiving chemotherapy with ethanol-containing docetaxel alone or in combination. Subjects who voluntarily provide written informed consent to provide information for this study and meet the inclusion/exclusion criteria will be given an enrollment number and will be followed during the observation period to collect study-related data in the Case Report Forms (CRFs) as predefined in the study protocol. Patients' decision to participate (or not) in this study will not affect their treatment (physician's prescriptions or diagnostic/therapeutic decisions).
Background: Prostate cancer is one of the most common cancers in men. For some men, their cancer is monitored. Others have surgery to remove the prostate. Focal therapy is another treatment option. It treats the areas of cancer selectively, which leaves the rest of the prostate intact. This can help lessen side effects. Men who get focal therapy must be chosen carefully. The Oncotype DX Genomic Prostate Score (GPS) assay tests biopsy samples for certain cancer-related genes. It then then gives a score from 1 to 100 to predict the likelihood of poor outcomes. The GPS is used to choose men for focal therapy. Researchers want to test the GPS further. Objective: To assess how GPS may be useful when used with MRI to improve how men are chosen for focal therapy of prostate cancer. Eligibility: Men age 18 and older who had NCCN low or intermediate risk prostate cancer and had MRI and radical prostatectomy at the Urologic Oncology Branch, National Cancer Institute and collaborating centers. Design: This is a multisite study. It will review data and samples that were collected in the past. Samples and images from up to 277 participants will be used. Tumor tissue will be tested with the GPS. Data such as age at diagnosis, race, biopsy results, and pathology results will be merged with the GPS results. Data will be entered into an in-house electronic system. It will be password protected. All data will be kept in secure sites that comply with NIH security standards.
This is a trial of 5 fraction SBRT combined with androgen deprivation therapy for patients with localized high-risk or unfavorable intermediate risk prostate cancer
The purpose of this phase I/Ib study is to determine the safety profile of Epidiolex (CBD oil) in biochemically recurrent prostate cancer patients. The study consists of a dose escalation part and dose expansion part. The dose expansion part of the study will use the maximum tolerated dose (MTD) determined in the dose escalation part to assess the activity, safety and tolerability of the investigational product in patients with biochemically recurrent prostate cancer after localized therapy with either surgery or radiation.
This is an open label, non-randomised, phase I, sequential group trial which will explore the safety and tolerability of ascending doses of AdNRGM, in combination with CB1954. Five groups of 3 patients each will be treated with escalating doses of AdNRGM (10^10, 3x10^10, 10^11, 3x10^11, 10^12 vp) followed 2 days later by intravenous CB1954 at a fixed dose (24mg/m^2). To ensure the coverage of the whole prostate the vector will be delivered by multiple, template-guided trans-perineal injections using an adaptation of standard prostate brachytherapy technique. Dose escalation will be dependent on safety and tolerability; at each dose-level, if dose-limiting toxicity (DLT) is seen in one patient, the cohort will be expanded to a maximum of 6 patients. If DLT is then observed in a second patient at that dose, no further patients will be recruited and the previous (lower) dose-level will be defined as the maximum tolerated dose (MTD). If DLT is seen in 0/3 or just 1/6 patients, dose escalation may continue.
to compare the efficacy of HIFU treatment with standard treatment in two situations: 1. as first-line cancer treatment, HIFU is compared to radical prostatectomy. 2. for patients with recurrence after external beam radiotherapy, HIFU treatment is compared to radical prostatectomy.
The primary objective of this study is to evaluate the safety and feasibility of Magnetic-Resonance(MR)-ultrasound image fusion-guided transrectal-based focal laser ablation (FLA) of prostate cancer using the Orion System, an investigational laser-based interstitial irradiation/thermal soft-tissue ablation system. Safety and feasibility will be determined by analyzing the number, type, and severity of adverse events.
The interpretation of prostate multiparametric MRI (mpMRI) is difficult and requires expertise. As a result, it suffers from substantial inter-reader variability. The so-called Prostate Imaging Reporting and Data System (PI-RADS) scoring system has been launched in 2012 to try and standardise prostate mpMRI interpretation. It is a 5-level score that assesses the likelihood that suspicious focal prostatic lesions seen on mpMRI are clinically significant prostate cancers. Despite the use of semi-objective criteria for each category of the score, the inter-reader reproducibility of the first two versions (PI-RADS v1 launched in 2012 and PI-RADS v2 launched in 2015) was moderate at best, even for experienced readers. The last version (PI-RADS v2.1) has been launched in March 2019 in an effort to improve the inter-reader reproducibility. This version has not been evaluated yet. The purpose of our study is to evaluate the accuracy and inter-reader reproducibility of the PI-RADS v2.1 score on a large set of 163 prostate MRIs using 20 readers of varying experience. Twenty readers (14 seniors and 6 juniors) from 7 different institutions and with varying experience in prostate mpMRI accepted to participate to the study. Reader will assess the dataset independently and will be blinded to the other readers' results. They also be blinded to clinical and biochemical data.
This is a prospective observational cohort study of patients with prostate cancer who have a metabolic syndrome. The study aims to evaluate the role of intermittent fasting (fasting mimicking diet) in these patients. The primary end point is metabolic health and the secondary endpoint is quality of life.
